Over 800 million people now don't have enough to eat. The number is increasing because of global heating — and because of population growth.

1/4 of young children are stunted by malnutrition. People who can't feed all their children need to have fewer.

Population growth accelerates global heating as well as decreasing crop yields. It will also reduce the nutritional value of many staple foods.

Please do your bit — don't have (more) children.
